AISI SAE 4130 4140 4145H Steel Round Bar Hollow Rod
Features
4130 4135 4140 4145H Serae ferreae sunt humile chalybe carbonis offensionis.Chrome-Molly stannum ea sunt quae chromium et molybdenum continet ut ministros corroborantes.
4130 Sera ferrea rotunda facultatem habet bonam operandi, processus minimam deformationem, et resistentiam optimam lassitudinem.Ad praedicationem medii pertinet ad facultatem ferro obdurare altam.Post curatio caloris, 4140 has bonas vires et proprietates mechanicas comprehensivae, bonae facultatis processus, altae cedunt.Temperatus est gradus 427. Servitium Celsius.
4140 Virtutem habet altam, facultatem obdurationis, duritiem, deformationem in exstinguendo.Subrepere est altum robur et patientiae robur in calidis.Usus est ad malleos fabricandos qui superiores vires requirunt et sectiones maiores exstinctas et temperatas quam 4135 ferro, ut anni magni ad tractionem motivum, anni cursus transmissionis, axes posteriores, virgas conectentes et tondeos vere oneratos.
